【PETLIBRO】Automatic Pet Feeder (Includes Instruction Manual)

Used a few times, but selling as I no longer have a need for it.
Below is the product description from when I purchased it.

ーーーーーーーーーーーーーーーーーーー
[Scheduled & Portion Controlled Healthy Feeding]: Set 1-6 feedings per day within a 24-hour period! You can set 1-50 portions for each feeding. Set it to dispense small amounts at regular intervals. This prevents pet obesity and vomiting due to morning hunger, providing your cat or dog with a balanced and healthy diet.

[4-Layer Freshness Preservation]: (1) Twist-Lock Lid: The automatic feeder's lid features a twist-lock mechanism to prevent pets from tampering with it and securely locks in freshness. (2) Desiccant Bag: A desiccant bag is built into the sealed lid to prevent moisture and dampness. (3) Sealed Food Tank: The silica gel sealing ring between the lid and the container effectively blocks air, preventing food oxidation. (4) Feeding Port: The rotating door has a unique design that closes immediately after dispensing food, preventing insects and pet chewing, and allowing for long-term food storage.

[Washable for Cleanliness and Hygiene]: Made with food-grade ABS material, it is durable and long-lasting. The stainless steel food bowl and bowl base are removable for easy cleaning, ensuring hygienic use. Additionally, the lid, food tank, and base are very easy to assemble, disassemble, and wash. The main unit cannot be washed with water; please wipe it with a tightly wrung-out cloth.

[Anti-Jamming Design]: The feeding port is equipped with an infrared sensor. When the bowl reaches a certain level, the machine automatically stops to prevent food from overflowing. The motor has a self-protection function that stops the motor from operating, preventing overheating and malfunction due to overload. It is compatible with dry food in sizes ranging from 2-15mm.

[Dual Power Supply for Power Outage Backup]: The automatic feeder can be powered by a 5V AC adapter or 3 D-cell alkaline batteries (sold separately). It has a memory function, so your feeding settings are saved even if the power is turned off. In the event of a power outage, it will operate on batteries, providing peace of mind during emergencies. (It is generally recommended to always use the power adapter, and use batteries only as a backup option for power outages.)
